Letters Patent No. 105,373, dated July/'12, 1870.y

`mummiaMem"in man MANUFATURE or BRUSHES.

The Schedule referred to in these Letters Patentand making part of the saute.

Be it known that I, CHARLES F. Rosate, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful. Improvement iri thel Manufacture of Brushes, of which the following is a full, clear, and exact description, referencebeing hadto the accompanying drawing formingpartof this specification, and in which- Figure 1 represents .a plan of amold or box, composed of or containing a perforated block made up of strips, for making brushes, in accordance with my im- `Figure 2, alongitudinal sectional elevation of the same, with a `follower therein, and as in the process of making a brush.

Similar letters of reference indicate corresponding' parts. I ,Y

My invention relates to b1nshes,`inwhich the bristicnlarly relates to such brushes, irrespective of any which the tufts are imbedded, through the agency of or any suitable material or composition capable of asbei'ng hardened; y

lhe inventipn consists in a divided striplike-cou struct-ion ofthe perforated block or` bottom of the mold, through which the looped tufts are drawn to secure the imbedding ot' them in the plastic back, the dividing lines of the strips being arrangedto run cenwhereby increased faclity'is afforded for removal of gering the loosening or extraction of vthe tufts in or A A represent sides and ends of a frame', mold, or box, held together by bolts c a., so as to admit of the a bottom to the mold. 'lhe perfor-ations c c.,v through arranged so that tli'ey are diametricaily divided by the strips, that is, each perforation is formed half its diameter in the'one strip and half in the adjacent sti-ip.

In making the brush, the tufts d d are looped iu the usual manner and passed through the perforations c c from below, till their looped ends4 0r portions project somewhat above the tops of the strips B B. To v facilitatethe passage of the tufts, and to give them a better hold in the brush-back, as well as to secure to,

them a free and` spreadingaction or arrangementon the-face of the back, Vthe perforations c c are of a diminishing taperinan upward direction.

The tufts ll d having beenV arranged in the mold or box, as shown and described, prepared India' rubber, gutta-percha,.or `other suitable material or composition, is introduced while in' a plastic state, in a suitable quantity, within the-moid abovmthe strips B B, so that, on. a follower, C, being brought down by a press action within the mold, said material or composition is compressed :into a solid mass of a coutgiuation corresponding with the interior of the mold and under side of -the follower, and which may either be plain or ornamental. This not only forms the brushback, but causes the looped endsv of -the tufts to he -imbedded therein, and, alter the material composing the back has been hardened Vor allowed to set, establishes a sccurehold of the tufts.

when lthe brush-may be removed and the tufts d d ,drawn out frombetwecn the-strips or perforations c c,

without endar gering the loosening or extraction of them in or from the back, by reason of .the dividing lines of the strips being made todiametrically intersect' said perforations.

What is here claimed, and desired to be secured by yLetters Patent, is-,-

The sectioually-constructed blockr ,or mold bottom,

haring perforations c cthrongh it, and made up oz" strips B B, arranged to intersect said perforations diametrically, in combination with the surrounding body of the mold, constructed to receivea'followerVG, within it, substantially ns specified` CH. F. RESET. Witnesses:
